PRESSER-FOOT FR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 765,619, dated July 19,1904. Application filed September l1, 1903. Serial No. 172,792. (Nomodel.)

To all whom it wila/y concern,.- l

Be it known that I, JACOB R. HANN, aV citizen of the United States,residing at Jackson, in the county of Jackson and State of Michigan,have invented certain new and useful Improvements in Presser-Feet forSewing-Machines, of which the following is a specilication. i

This invention relates to sewing-machine attachments, and moreparticularly to the presser-foot, and is designed to prevent skipping ofstitches of sewing-machines of ordinary or special construction byproviding a foot of novel formation and comprising elements or memberswhich will exert a uniform pressure upon different thicknesses of goodsor work comprising two or more layers or folds.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreffecting the result reference is to be had to the following descriptionand drawings hereto attached.

While the essential and characteristic features of the invention aresusceptible of modiiication, still the preferred embodiment of theinvention is illustrated in the accompanying drawings, in which- Figure1 is a perspective view of a multiple or gang presser-foot. Fig. 2 is asection on the line X X of Fig. l looking in the direction of thearrows. Fig. 3 is a vertical central longitudinal section on the line YY of Fig. 1. Fig. 4 is a section of the complete foot on the line Z Z ofFig. 3. Fig. 5 is a perspective view of the guide and stop-frame.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

vstop 3 and the presser vmembers or elements 4, which are pivoted to thehead 1, so as to have independent movement, each being forced downwardby a spring 5. Any number of presser members or elements 4 may be theears 6 to receive the rod or pin 7 by means 4 of which the parts 4 and1-- are pivotally connected. The presser members 4 are curved upward attheir outer or front ends, as shown at 10, and engage with the cross-bar11 of the frame 3. The springs 5 are approximately of U form and receivethe pin or rod 7 in the bight or fold, the free ends of the membersengaging with, respectively, the head 1 and the member 4, as shown mostclearly in Fig. 3. Any suitable means may be provided to preventdisplacement of the springs, and, as shown, the outer ends of the uppermembers are upturned to enter a depression 12 of the head 1, asindicated most clearly in Fig. 3.

- The combined guide and stop-frame 3 is of U form` and its side members13 have inner flanges 14 at their rear ends to overlap the terminalportions of the head 1 and receive the fastenings by means of which theframe is attached thereto. A Acompanion bar 15 is spaced from thecross-bar 11 and is connected at its ends thereto, and the space formedbetween the two bars 11 and 15 is adapted to receive a tape, strip, orreinforcement when it is desired to stitch the same to the article beingsewed.

When the parts are assembled, the presser members or elements 4 are inline, and by reason of their pivotal connection with the head 1 and thecooperation of an independent spring with each said members are adaptedto yield to accommodate themselves to inequalities and differences ofthickness in the goods being stitched, so as to eXert a pressurethereon, which is essential to obviate skipstitching.

Having thus described the invention, what is claimed as new is# 1. In apresser-foot for sewing-machines,

IOO

from the head and having a cross-bar under- I5 lappinggthe outer ends ofthe presserzmembers to form a stop therefor an'd normally hold the samein alinement and having a com- Apanion bar spaced from said cross-barand connected at its ends therewith, substantially 20 as set forth. Y

In testimony whereof I aiix my signature in presence of two witnesses.
